TEACH ME ABOUT BI-WIRE

How 'bout we teach you about the search function here where you will find several threads on the subject that even cite websites where you can find speaker designers thoughts on the subject.

sfrounds- you are only half right. The speakers need to be set up to biwire, with separate + & - for LF and Mid/HF on each side. The amp, however, can and typically does have only one set of outputs. Imagine 2 + and 2 - for each channel at speaker end (for LF and Mid/HF). Then imagine the two + terminated together at the amp end, and the
2 - also terminated together. Therefore, there are two terminations per channel at the amp end, 4 per channel at the speaker end. In actuality, the cables can be entirely separate (just terminated together at the amp end) in a dual or shotgun biwire, or there can be + LF and + mid/HF together inside one jacket and - LF and - mid/HF in another jacket (called internal or single biwire).

Kinda a slow day/I'll tell you how/ what little I know; (this should be a very short story) If your speakers have what you described / It matters not, about the double posts on the amp end. You can buy an identical pair of wires/double them on the posts, at the amp end, then one pair to the low and one pair to the high terminal for each speaker/wala!! thats it. Yes, If you have a pair made for biwiring ,it is easier.That would mean there would be 1 spade on the amp end / 2 spades on the speaker end / A total of 4 pieces/ and no need for the double posts on the amp. Just about any speaker with such an arrangement, benefits from this. If you were to use 2 amps ;this is called bi-amping/If they are identical amps/this is usually better/but more costly.The speaker does love to "see" a feed from the amp for the highs and lows separately,for reasons my second grade education keeps me from explaining/but not to worry. For you; the second pair, from the same mfg. used, and probably available here, is the cheapest way to go.Welcome to the club!!
